Free macro calculator to find your daily protein, carbs, and fat targets for weight loss, muscle gain, or maintenance.
Macros are calculated based on your calorie needs and dietary preferences. Here's the breakdown:
Macro formulas:
Key insight: Macros are personalized. This calculator adjusts based on your goals, activity level, and dietary preferences.
Result = Validated health or fitness equation applied to the measurements and options entered. Review the methodology and limitations before interpreting the estimate.The calculator applies the selected body, age, activity and goal assumptions to a standard planning equation. Actual needs vary with health status, climate, training, medication, food measurement and changes in body weight or activity.
A macro calculator helps you find the specific grams of protein, carbs, and fat your body needs per day to reach your personal health, fitness or diet goal. “Macros” is the slang word used for macronutrients, which the three types of calories consumed in your diet. These are protein, carbohydrates and fats. Rather than simply aiming for a number of calories every day, a calculator helps you to know what percentage of each macro to include within this overall sum. Body builders use macros as do people that wish to lose fat, get fit or build muscles. If this is for you then this may prove to a helpful starting tool.
A macro calculator is not only for gym nuts! It can be used anywhere that planning precise nutrition is important.
Everyone from nutrition students, coaches setting up what clients should eat, to busy people just trying to eat intelligently, has used this.

Heavier and more muscular people tend to burn more calories at rest, and thus require more in terms of total macros and protein.
The condition of metabolism deteriorates as we get older, making us more likely to require fewer calories and put the optimum ratio of protein to calories for muscle preservation into a different range.
Men tend to carry more body muscle and have a higher resting metabolic rate, therefore men will have higher calories and protein targets than women of a similar weight.
If you run five days a week, you’ll require way more total daily calories and carbohydrates than your co-worker who sits at a desk all day, every day.
A caloric deficit (losing fat) for fat loss, from base TDEE will actually decrease your total macros and a surplus (gaining muscle) for potential muscle gain will actually increase your total macros, especially your carbs and protein.
Typically, the taller an individual, the more lean tissue they carry, and the higher their metabolic rate. This increases all baseline calorie and macro demands.
Things like hypothyroidism, insulin resistance, or pcos do change the way your body metabolizes calories and thus your ideal macros ratio may change.
Two people of equal weight but with differing levels of body fat will require varying calories needs because the human body uses more calories to maintain muscle mass compared to body fat.
Macros, short for macronutrients are these three nutrients that provide calories. These are protein, which provides 4 calories per gram, carbs which provide 4 calories per gram, and fats which provide 9 calories per gram. All foods consist of some ratio of these three elements, with water, vitamins and minerals providing no calories.
First, determine your total daily caloric intake using your height, weight, age and activity level. Next, determine the best percentage split for what you want to achieve (a good baseline for balanced weight loss is 40% carbohydrates, 30% protein, 30% fat). Convert the remaining amount to grams for each macro food group 4 for carbohydrates and protein, 9 for fat.
A lot of people are successful with a ratio around 40% carbs, 30-35% protein and 25-30% fat when creating a calorie deficit. When you take this amount of protein, your metabolism stays boosted because you're preserving muscle Mass to a great extent while dropping fat.
Active adults, particularly recreational ones, are often fine getting 0.7 to 1 gram of protein per pound of body weight. If muscle gain is the primary goal and someone is in a calorie deficit (dieting with severe restriction of daily calories for an adult male [8 to 12 percent])... They likely need more.
That’s not always the case. There are approaches like carb cycling which involves eating a good amount of carbs on days when you train and significantly less on your days off while keeping your protein intake high across all the days to optimize performance, training capacity and recovery while not changing the overall week energy intake much.
These are a good starting point, as formulas like the Mifflin-St Jeor ones are good, but reality is always going to have differences due to genetics, individual hormones, and how your tracking devices perform (or lack there of). Most people will change these targets after a couple of weeks.
Use current measurements and a realistic activity level. Follow the estimate consistently, monitor results over time and adjust only after comparing actual progress, hunger, performance and professional guidance.
The first step the calculator takes to estimate the number of calories burned in a day will be to estimate your Basal Metabolic Rate (BMR) based on your results using the Mifflin St Jeor calculation, which many dieticians claim is more accurate for most populations. The result of your BMR will then be adjusted based on your activity level, with your TDEE or your total daily expenditure, then being calculated.
After it determines your TDEE, the calculator takes your goal, sets your total calories (loss, maintain or gain), and breaks them into protein, carbs and fat using the percentages that correspond to your goal.
Here's the basic process behind every macro calculation:
Consider a 30-year-old woman who weighs 150 lbs, is moderately active, and wants to lose fat:
Her daily targets would land around 150g protein, 135g carbs, and 67g fat starting point she can adjust after two to three weeks based on real progress.
Don’t consider the first number as gospel, take it as a starting base only. For one to two weeks accurately calculate and log your foods using a food scale or app, analyse your trends on the scales and energy levels. Should you be cutting for fat loss and nothing happens after two weeks of dieting adjust by another 5-10% from your intake.If you’re trying to bulk for muscle and gained too quickly adjust calorie intake back slightly to minimize fat gaining.
Getting adequate protein amounts is the most crucial part for body composition. There is some flexibility when it comes to carb and fat amounts- it’s usually ok to adjust some grams between these two every day as the total amount of calories and total protein remain the same.
